Resolution and Determination of the Absolute Configuration of a Twisted Bis-Lactam Analogue of Tröger's Base: A Comparative Spectroscopic and Computa…

2015

The first reported twisted bis-lactam, a racemic Tröger's base (TB) analogue (2), was resolved into its enantiomers on a chiral stationary phase HPLC column. The absolute configuration of (+)-2 was determined to be (R,R)-2 by comparing experimental and calculated vibrational circular dichroism (VCD) and electronic circular dichroism (ECD) spectra. The absolute configuration of (-)-2 was determined by comparing experimental and calculated electronic circular dichroism (ECD) spectra. The corresponding theoretical spectra were calculated using the lowest energy conformation of (R,R)-2 and (S,S)-2 at the B3LYP/6-31G(d,p) level of theory. The absolute configuration of (+)-2 was also determined t…

Benthic foraminifera as indicators of relative sea-level fluctuations: Paleoenvironmental and paleoclimatic reconstruction of a Holocene marine succe…

2017

This study presents the results of an integrated stratigraphic analysis conducted on a marine gravity core (MSK-12 C4) recovered from the outer continental shelf (82 mwater depth) of western Calabria, ~2.6 km, NE of Capo Vaticano (Eastern Tyrrhenian margin). The gravity core MSK-12 C4 recovered a stratigraphic succession of 4.18 m beneath the seafloor representing the last ~11.1 ka. Sedimentological analysis, micropaleontological quantitative analysis on benthic foraminiferal assemblages, tephrostratigraphy, sequence stratigraphic analysis of high resolution reflection seismic data recorded in the core site area and AMS 14C absolute age determinations allowed reconstructing the marine recor…

Sobre algunos conceptos básicos de la filosofía de Hegel

2007

La Enciclopedia filosófica para los últimos cursos de bachillerato (1808 y ss.) es uno de los textos que Hegel escribe a partir de 1808 para la docencia en el Instituto de enseñanza media de Nuremberg. Este texto anticipa la Enciclopedia de las ciencias filosóficas de Heidelberg y Berlín, que es el centro de la obra de Hegel. Podemos, pues, entender que esta pequeña enciclopedia de Nuremberg tiene un carácter introductorio respecto de la Enciclopedia de las ciencias filosóficas y, por tanto, respecto de la obra de Hegel en general, posterior a la Fenomenología del espíritu. Lo que voy a hacer aquí es una introducción a esta introducción, es decir, voy a hacer una introducción a algunos de l…

La noción de lo absoluto en la Fenomenología del espíritu de Hegel

2009

Una de las tesis más enfáticamente subrayadas por Hegel en el «Prefacio» de la Fenomenología del espíritu es que el Absoluto, o lo Absoluto, hay que pensarlo no sólo como sustancia sino también como sujeto. Pero como ese «también» no debe entenderse como «además», sino como un cancelarse lo primero en lo segundo, la frase tan enfáticamente subrayada por Hegel tiene el sentido de que lo Absoluto no hay que pensarlo como sustancia, sino que, partiendo de ésta, hay que pensarlo como sujeto, o mejor: que esa sustancia tiene que acabar siendo pensada como sujetualidad. Ahora bien, si por sujeto entendemos una sustancia pensante (y si además prescindimos de los referentes históricos, sobre todo S…

Tema 1. Poder y Sociedad en el Mundo Moderno: Estado, absolutismo y constitución en la Edad Moderna

2014

En el primer tema de la asignatura "Poder y Sociedad en el Mundo Moderno", de cuarto curso del Grado de Historia, se repasan varios los conceptos clave para entender la vida política de la Edad Moderna, no sólo el de Estado moderno, sino también los de absolutismo, estamentos, prerrogatigas, imperio, etc., y se analiza, entre otras cuestiones, el constitucionalismo de tipo antiguo y la sacralidad regia.

Factorization of strongly (p,sigma)-continuous multilinear operators

2013

We introduce the new ideal of strongly-continuous linear operators in order to study the adjoints of the -absolutely continuous linear operators. Starting from this ideal we build a new multi-ideal by using the composition method. We prove the corresponding Pietsch domination theorem and we present a representation of this multi-ideal by a tensor norm. A factorization theorem characterizing the corresponding multi-ideal - which is also new for the linear case - is given. When applied to the case of the Cohen strongly -summing operators, this result gives also a new factorization theorem.

Operator martingale decomposition and the Radon-Nikodym property in Banach spaces

2010

Abstract We consider submartingales and uniform amarts of maps acting between a Banach lattice and a Banach lattice or a Banach space. In this measure-free setting of martingale theory, it is known that a Banach space Y has the Radon–Nikodým property if and only if every uniformly norm bounded martingale defined on the Chaney–Schaefer l-tensor product E ⊗ ˜ l Y , where E is a suitable Banach lattice, is norm convergent. We present applications of this result. Firstly, an analogues characterization for Banach lattices Y with the Radon–Nikodým property is given in terms of a suitable set of submartingales (supermartingales) on E ⊗ ˜ l Y . Secondly, we derive a Riesz decomposition for uniform …

Ar dabas aizsardzību saistīto terminu lietojums uzņēmumu mājas lapu tekstos

2021

Uzņēmumi savās mājas lapās var izmantot ar dabas aizsardzību (DA) saistītus terminus, lai sabiedrība tos uztvertu noteiktā veidā. Šī bakalaura darba mērķis ir analizēt DA terminu lietojumu desmit izvēlētu uzņēmumu mājas lapu tekstos, kas ņemti no piecām dažādām nozarēm. Galvenās pētījuma metodes ir literatūras apskats, absolūtā biežuma analīze un diskursa analīze. Dati parāda, ka automašīnu ražotāji savās mājaslapās izmanto visvairāk DA terminu, savukārt apģērbu firmas izmanto vismazāk DA terminu. Lielākā daļa atrasto DA terminu ir lietvārdi. Tiek secināts, ka uzņēmumus, kas savās mājaslapās lielākoties izmanto DA terminus no „vides risinājumu” kategorijas, var uztvert kā dabai draudzīgākus…

Natural and anthropogenic influences on the geochemistry of Quaternary lake sediments from Holzmaar, Germany

1997

The accumulation of heavy metals and trace elements has been investigated in a well laminated sequence of Holocene and late Pleistocene lake sediments composed of diatomaceous gyttja, tuff and silt and clay sediments. Varve chronology of the annually deposited gyttja yielded a continuous high-resolution time sequence and allowed the absolute age dating of the sediment. Fluxes of elements remained largely uniform from the late Pleistocene into the Holocene. Higher trace element and heavy metal fluxes occur from 2322 to 862 VT years ago (VT: varve time, years before 1950) and reached their maxima in the uppermost sediments (<845 VT years ago). These increasing element fluxes correlate with in…
